South Sydney say Sam Burgess has not discussed a release from his contract despite a report that he will switch to rugby union at the end of the year.

Britain's Daily Mail reported on Thursday that the England international rugby league forward had accepted a three-year deal with an English rugby club, believed to be Bath, in the hope of playing at the 2015 World Cup.

Burgess's departure from rugby league was expected to be confirmed once financial terms – including an estimated £500,000 ($A920,000) transfer fee – had been finalised, it reported.

Burgess has been a key figure in South Sydney's re-emergence as a rugby league powerhouse since being recruited by owner Russell Crowe in 2010 and he is contracted to the club until the end of 2016.

In response to the speculation the Rabbitohs sent a statement to club members.

"The club has had no contact from Sam's management, the Rugby Football Union or any rugby union clubs in the UK regarding a release for Sam Burgess from his NRL contract with the Rabbitohs," the statement read.

Souths captain John Sutton said it would be a big loss, on and off the field, if Burgess departed.

"He is a great player," Sutton said. "Ever since he came to Souths he has been a leader.

"He would be a big loss if he does go, but I don't know anything about that."

NSW Waratahs coach Michael Cheika, who spent eight years coaching in Europe, said he believed Burgess could be a success in the 15-a-side code, with talk suggesting he would play in the centres.

"He's a pretty competitive type of guy, he's a big, athletic player. The basics of the game are relatively the same and he's still young. I'm sure he'll go well if he does make the move," Cheika said.

But Waratahs playmaker Bernard Foley wasn't so sure.

"It's not as easy as everyone says to switch codes," he said.

"For a bloke like Sam Burgess he's a great athlete and I'm sure he'll have a really good crack at it but I don't think it's as easy as everyone says to swap over and just go in for a World Cup.

"Especially going into an England side that's been preparing for the last couple of years and looking pretty stable."
